Powerful buck DC/DC converter with adjustable output voltage stabilized and adjustable maximum current. Made using synchronous rectification technology on the LM25116 microcircuit and two IRFB3607 field-effect transistors.
Adjustment of current and voltage is carried out using trimming resistors installed on the board. The output current can reach 20 A. The module is equipped with overcurrent protection, overheating protection, short circuit protection.
Great for powering LEDs, building chargers, just a regulated converter, or a module for a laboratory power supply.

Maximum output current: 20 A
Efficiency: ≤ 95%
Overload protection: yes
Overheating protection: yes
Short circuit protection: yes
Working temperature range: -40 ... +85°C
Module dimensions: 60 x 53 x 27 mm
Pinout of terminal blocks:
IN +: "plus" input supply voltage
IN-: "minus" input supply voltage
OUT +: "plus" output voltage
OUT -: "minus" output voltage
Adjustment:
CV: output voltage adjustment
CC: output current adjustment
When working with this module, it is worth considering some of its features:
If the radiator heats up more than 60 degrees, you need to install active cooling (fan), otherwise it may fail
The input/output voltage difference must be at least 2V. The output voltage cannot be more than the input voltage.
When using a converter, the "minus" of the input and output must be galvanically isolated (not connected), otherwise the current sense resistor will be "short-circuited" and the maximum output current limitation will not work. This can lead to module overload and failure.
